SAFETY-LOCK.

To all zr/um it may conccrn Be it known that 1, WILLIAM F. iVaLnnu,

a citizen of the United States. and a rosidcnt of the city of Chicago, county of Cook, and State of lllinois, have invented certain new and useful Improvements in Safety- Locks, of which the following is a specification.

My invention relates to improvements in safety locks especially adapted for use in conjunction with automobiles and the like, and has fol-its object the provision of a simple device of this character which will effectually prevent unauthorized removal of an automobile or the like.

The invention consists in the combinations and arrangements got parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in Figure 1 is a face view of a device embodying my invention, Fig. 2 a face view of the device with parts removed and other iarts shown in section, Fig. 3, a vertical section of the device, Fig. l, a perspective view of a slidable bolt employed in the construction, and Fig. 5. an enlarged section taken through a combination lock employed in the device.

The. preferred "form of construction as illustrated in the drawings comprises a suitable casing 1 adapted to be secured to the dash board or other convenient part of an automobile, said casing being;- provided with a removable closure .2, as shown. At its upper end casing 1 is provided with inwardly projecting locking lugs and closure 2 is provided'with locking lugs -l adapted to engage lugs 3 and prevent direct outward removal of the corresponding end of said closure, as will be readily understood, said lugs being so arranged as to permit the proper positioning of closure 2 by tilting the lower end the out. At its lower end closure 2 provided with an upwardly extending locking lug 5 adapted to engage a downwardly extending locking lug lorincd on the lower end of a metallic plate 7 secured to the upper end of a bolt 8 slidably mounted in casing l and preferably made. of hard fiber or other insulating material. Plate 7 carries a pin 9 which projects outwardly Specification of Letters Patent.

through a slot 10 in closure 2, said closure being provided with a swinging keeper 11 adapted to engage pin 9 and hold said pin in the lower portion of slot 10, as indicated in Fig. 1. Bolt 8 provided at each side with a perforated ear or lug l2 sliding upon guide pins 1 arranged in casing l, as shown and compression springs 14- are placed on pins 13 between lugs 1.2 and the bottom of casing 1, said springs tending to pre bolt 8 upwardly, as will be readily imdeis'rood. lly-this arrangement, it will be observed that when bolt 8 is depressed by depressing pin 9, lug 6 engages lug 5 and positively loclrs closure 2 in closed position, as long as bolt 8 in depressed. position tl positively preventing tampering with the mechanism within casing 1.

Bolt 8 cooperates with a combination loci-z arranged on. closure 2 in the upper portion of casing 1, said combination locl: comprising two combination plates 15 which are retatably mounted on a hollow hearing or hub 16 formed integrally with the closure 2, as shown in Fig. .7. These plates 15 are the usual combination plates employed in locks of this character and are provided with notches which, when in registration with ach other, permit the elevation oi bolt 51. Plates 15 are separated by a spacing ring 17 as shown. in operating stem 15 cutends through bearing; 16 and is provided with a squared projection Il on its inner end. A third c inbination plate 20 similar in all respects to plate 15 is secured to the inner end of stern 18 by means of a suitable screw and washer 21, as will be readily understood, and a distancing ring placed between the outer plate 15 and plate 20 as shown. The specific form of mounting for plates 15 and LO constitutes a simple and ellicient one for the purpose and a construction in which the parts may be securely mounted in opcrative positions without danger of binding between the dillerent plates of the combination.

it. its outer end stem 18 is plnvided with an operating handle 93 in which lS arranged a spring ield ball 2i, said ball being positioned to cooperate. with and euter heiuispherical recesses provided in the bars "26 ol the dial of the combination formed on the face of closure By this arrangement it will be observed that as handle registers the bottom with each of the cars 26 the ball 24; will click in the corresponding recess thus notifying the operator when the pro ei' com ination has been eiiccte i. Each the plates coal is pi'ovicletl with a. plurality oi decoy or false notches 52'? which are not deep enough to permit the entry of the upper end of colt 8 fez-enough to disengage shoulders 6 uucl 5. By this arrangement a person sttempting opeiote the combination by the sense oi": feeling; 01 hearing lcscl oy these decoy notches and thus prevented from setting the combination.

A. guard tube 28 extends downwardly from of the casing 1 anal c. rocl 29 passing through said tube connects bolt 8 with a valve 30 as shown. Volvo 30 operates I in a valve casing 31 cutl serves to open and 1 below close-tho through soiil valve casing,

said valve cs sing being connected in the fuel pipe 32 leading to the engine of the automobile, so that valve 30 thus controls the supply of fuel to the eugi ie, saiil supply being intci'ruptcal when oolt 8 is depressed, es "ill be readily uurleietoofi. A pair of electric contscts 33 is oriimgezl iii casing 1 on opposite sides of lit-it Su ousuitsble insulctiug blocks, as indicator and. another pair of electric contacts 34% are arranged in casing 'coutocts 331, as shown. A metallic connecting coisecured to-bolt 8 in positiou to connect either contacts 33 when bolt 8 is clevctecl, or contacts 34 when bolt 8 is depressed. Electric wires 33 ore connected with contacts 33 and Wires 37 are connected with contacts 3 said wires 3% serving to connect contacts 33 in series with the battery circuit of --the automobile and Wires 37 serving; as a means for gi'ouncliug the magneto.

In use casing l is securccl to the ordinary clash bosnl oi the automobile 21ml contacts 33 connectecl in series with the battery and contacts connectel in series with the mo neto and grooves. The valve casing 31 is inserted in the fuel supply pipe of the engine will he reatlily uui lerstoorl. "When it is desirecl to lock an autoifiobile against unauthorized removal, pin 9 is clepresscol thereby breaking the battery circuit of the engine, closing the grouml ciruit of the magneto and also closing the fuel supply pipe so as to cut oil the supply of. :fuel from engine. 'Pin 9 is locked in depressed position by keeper .1 and handle 523 is turned so as to throw the combination of the combination lock and prevent elevotio'ooif bolt 8. This will etiectuelly prevent uuoutlioused starting of the engine and consei' uont removal of the automobile. l -J'hcu it is llcsiscil to start the car, the comloinution is incuipulatecl to permit elevation of bolt '8 Silltl comsi mticii being only in the knowledge of one authorized to 0percte the can, it can only he pvfoperly, set lo;

woulcl be misother. substantially as (lescri such a person. Then keeper 11 is removefi to permit elevation of bolt 8 under the influence of springs l t. This closes the list terycircuit and breaks the grouiicl of the magneto thus permitting the formation of sparks in the engine from either source, at the some time the fuel supply pipe is opens/cl to permit the passage of fuel to the engine. In case it is desired to inspect the interior of casing for repairs or otherwise, this may be clone when bolt 8 is in elevated position. It will be observed, however, that the closure 2 cannot be removed when the looking clevicc is set at safe position. owing to the engagement of shoulder 6 with shoulder 5, thus preventing tampering with the cm or, remov ng the closure 2. v

While I have illustrated aucl clcsciioetl the preferred form. of construction for carrying; my invention into effect, this is capable of \HIlZIiZlOH and modification Without (leparting from the spirit of the invention. 1,

therefore, do not wish to be limited to the precise details of construction set forth, ut desire to avail myself of such variations out mocliiicotious us come within the scope of the appended claims.
